Syntace QR 15 adjustment puzzle. (X Fusion)

I've fitted an X Fusion Slant. The Syntace 15mm lever sits at 6 o'clock, pointing straight down when fully tightened, so clearly needs adjusting. I've tried adjusting it with the cap screw but cannot work out how to adjust it. Can anyone give me an idiot style step by step guide to making the lever point upwards when fully closed please?
